Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 207608-3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Number of positions (3)
• Pitch - mating (0.197" / 5.00mm)
• Mounting type (Through hole, right angle)
• Contact type (Female socket)
• Current rating (7.5A)
• Voltage rating (600V)
• Operating temperature range (-55°C ~ 130°C)
• Contact finish - mating (Gold)
• Insulation material (Thermoplastic)
• Flammability rating (UL94 V-0)

The substitute part 207608-7 meets all mandatory matching parameters. Differences exist only in packaging format and post-contact finish composition, which do not affect electrical or mechanical compatibility in the mating interface.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 207608-7

The 207608-7 is the direct substitute for the 207608-3. Both connectors share identical electrical and mechanical specifications across all mating interface parameters. The 207608-7 is the active production variant within the Metrimate series.

Compliance Considerations:

The 207608-7 carries RoHS Compliant status, whereas the 207608-3 is marked as "Not applicable." This distinction reflects the 207608-7's compliance with Restriction of Hazardous Substances regulations. The post-contact finish differs between the two parts: the 207608-3 uses tin-lead, while the 207608-7 uses tin. This change aligns with RoHS compliance requirements and does not affect mating interface performance.

Product Status Impact:

The 207608-3 is obsolete, while the 207608-7 is active. For new designs, ongoing production, and long-term supply chain planning, the 207608-7 is the appropriate selection. The 207608-7 maintains full backward compatibility with existing mating connectors and cable assemblies designed for the 207608-3.

Frequently Asked Questions (FAQ)

Q: Can the 207608-7 directly replace the 207608-3 in existing applications?

A: Yes. The 207608-7 is electrically and mechanically equivalent to the 207608-3 across all mating interface parameters. Both connectors feature identical pitch, contact configuration, current and voltage ratings, and operating temperature range. The 207608-7 is compatible with existing mating connectors and cable assemblies.

Q: What is the difference between the tin-lead post finish on the 207608-3 and the tin post finish on the 207608-7?

A: The post finish is the plating applied to the solder tail of the connector. Both finishes support soldering to PCBs. The tin finish on the 207608-7 reflects RoHS compliance requirements and does not affect electrical performance or mating interface compatibility.

Q: Why is the 207608-3 marked as obsolete?

A: The 207608-3 has been superseded by the 207608-7 in the active product line. The 207608-7 offers the same functionality with RoHS compliance and active manufacturing support.

Q: Does packaging format affect connector compatibility?

A: No. The 207608-3 and 207608-7 differ in packaging (the 207608-7 is supplied in trays), but packaging does not affect the connector's electrical or mechanical performance. Packaging differences relate only to order quantities, storage, and handling logistics.

Q: Are there any temperature or current limitations when substituting the 207608-7 for the 207608-3?

A: No. Both connectors operate across the identical temperature range of -55°C to 130°C and support the same 7.5A current rating at 600V. There are no derating or operational limitations introduced by the substitution.

Q: What is the contact material for both connectors?

A: Both the 207608-3 and 207608-7 use phosphor bronze as the contact material with gold plating on the mating surface. This ensures consistent contact resistance and reliability across both parts.
